Spectacle frame for telemicroscopes and the like

Abstract

An improved spectacle frame for use with a telemicroscope or similar optical instrument. The spectacle frame includes temple pieces which are angularly disposed with respect to the lenses mounted in the spectacle frame, nose pads which extend toward the tip of the user's nose, rather than the eyes, and a uniquely designed, elevated bridge assembly. Optionally, a second pair of conventionally mounted nose pads may be provided. These features combine to achieve a more favorable positioning of the telemicroscope with respect to both the lenses of the spectacles and the eyes of the user, both to maximize the field of view and to improve the pantoscopic angle, and also improve weight distribution to minimize chafing, soreness and fatigue.

I claim: 
     
       1. A spectacle frame in combination with a telemicroscope capable of having a pair of lenses mounted therein, said frame comprising: a pair of temple pieces for supporting said frame on the ears of a wearer;   a brow bar interconnecting said pair of temple pieces and crossing the wearer's face above the eyes thereof, said brow bar having a pair of opposed ends, one of said ends being pivotally connected to one of said pair of temple pieces, and the other of said ends being pivotally connected to the other of said pair of temple pieces;   a pair of lens encircling rims depending from said brow bar;   an elevated bridge assembly disposed on said brow bar at a location medial said pair of depending rims for mounting a telemicroscope including a pair of objective lenses and a pair of eye piece lenses thereon; and   a nose pad member for supporting said frame on opposite sides of the bridge of the nose of said wearer, said nose pad member being mounted on said rims and extending in a direction away from said temple pieces.   
     
     
       2. The spectacle frame of claim 1 wherein said temple pieces are angularly disposed with respect to said pair of rims such that a plane coincident with a pair of lenses mounted in said rims is substantially perpendicular to optical axes defined between each of said wearers eyes and the respective objective lens of the telemicroscope. 
     
     
       3. the frame of claim 1 wherein the elevated bridge assembly further includes an elevated bridge piece and a pair of tapering side supports connecting said bridge piece and said brow bar. 
     
     
       4. The frame of claim 1 wherein the brow bar further comprises a side extension formed at each end thereof and extending for a short distance around the sides of the wearer's head, said temple pieces being pivotally mounted to said side extensions. 
     
     
       5. The frame of claim 1 wherein said nose pad member is a single string nose pad. 
     
     
       6. The spectacle frame of claim 5 wherein said temple pieces are angularly disposed with respect to said pair of rims such that a plane coincident with a pair of lenses mounted in said rims is substantially perpendicular to optical axes defined between each of said wearer's eyes and the respective objective lens of the telemicroscope. 
     
     
       7. The frame of claim 1 wherein said nose pad member is a pair of opposed nose pads. 
     
     
       8. A spectacle frame in combination with a telemicroscope incapable of having a pair of lenses mounted therein, said frame comprising: a pair of temple pieces for supporting said frames on the ears of a wearer;   a brow bar interconnecting said pair of temple pieces and crossing the wearer's face above the eyes thereof, said brow bar having a pair of opposed ends, one of said ends being pivotally connected to one of said pair of temple pieces, and the other of said ends being pivotally connected to the other of said pair of temple pieces;   a pair of lens encircling rims depending from said brow bar; and   an elevated bridge assembly disposed on said brow bar at a location medial said pair of depending rims for mounting a telemicroscope including a pair of objective lenses and a pair of eye pieces thereon.   
     
     
       9. The frame of claim 8 wherein said temple pieces are angularly disposed with respect to said pair of rims such that a plane coincident with a pair of lenses mounted in said rims is substantially perpendicular to optical axes defines between each of said wearer's eyes and the respective objective lens of the telemicroscope.
